ICPMSMS
ICPMSMS, short for inductively coupled plasma tandem mass spectrometry, is an analytical technique that combines an inductively coupled plasma ion source with a tandem mass spectrometer to enable highly selective and sensitive elemental analysis at trace levels. It is typically implemented as an ICP-QQQ-MS, using three mass filters: first quadrupole (Q1), a collision/reaction cell in the middle, and a second quadrupole (Q3) for analysis of product ions.
In operation, Q1 selects precursor ions based on their mass-to-charge ratio. These ions enter the collision/reaction
The method offers advantages such as improved selectivity, lower backgrounds, and better detection limits compared with
Common applications span environmental monitoring (trace metals in water, soil, and sediments), food safety (containment of
